1. WHAT HRF IS AND WHAT IT IS USED FOR
This product’s full name is HRF* 100 micrograms powder for injection. In this leaflet it is referred to
as HRF.
The powder in the vial contains 100 micrograms of the active ingredient gonadorelin as gonadorelin
hydrochloride and lactose monohydrate.The powder is dissolved in 1 ml of sterile water for injections
before use.
Gonadorelin is a synthetically produced hormone which is the same as a naturally occurring hormone
(LH/FSH-RH).
HRF is used to help check whether the hormones called luteinising hormone (LH) and folliclestimulating hormone (FSH), which occur naturally within the human body, are being produced and
released at the correct levels.
LH stimulates egg production (ovulation) from the ovary in the female, and the hormone testosterone
from the testicle, in the male. FSH stimulates the ovaries to release eggs, and the testicles to produce
sperm.
2. BEFORE YOU TAKE HRF
Do not take HRF if you:
•
•
•

are allergic (hypersensitive) to HRF, similar medicines, or to lactose.
are, or suspect you may be, pregnant

HRF may provoke early ovulation in women. If you rely on the timing of your menstrual cycle to
avoid pregnancy, then you need to be aware of this risk.
HRF injection is not recommended if you have a brain tumour called a pituitary adenoma.

your doctor or pharmacist for advice before taking any medicine.

3. HOW TO TAKE HRF
HRF should be given in a hospital under the supervision of an appropriate healthcare professional.
Dosage
The powder is dissolved in 1 ml of sterile water for injections before use.
HRF is given by means of a small injection under the surface of the skin or into a vein.
The doctor or nurse will take several blood samples before and after you receive the HRF injection to
monitor hormone levels.
In women, the HRF injection should be given in the first week of the menstrual cycle.
If you take more HRF than you should
This is unlikely, since you will be given HRF by a healthcare professional. Large doses do not seem to
produce any unwanted effects which are not seen at normal doses.
If you forget to take HRF
This is unlikely, since you will be given HRF by a healthcare professional. If you suspect that you
have not been given HRF correctly then contact your doctor.
If you have any further questions on the use of this product, ask your doctor or pharmacist.

4. POSSIBLE SIDE EFFECTS
Like all medicines, HRF can cause side effects, although not everybody gets them.
Allergic reaction
Allergic reactions have occurred on rare occasions after several doses. These may produce a wheezing
cough, a rapid heartbeat, flushing, rash, swelling, itching, redness of face, eyelids and lips, or a hard
lump at the injection site.
Menstrual cycle changes
HRF may interfere with women’s menstrual cycles, causing early ovulation. If you are practising the
rhythm method of contraception you should employ a barrier method of contraception for the period
of treatment, or take other steps to avoid unwanted pregnancy.
HRF may cause heavy and/or prolonged menstrual periods (menorrhagia).
Rare side effects
Headaches, nausea, lightheadedness, stomach discomfort or hot flushes.
Local side effects
Occasionally, swelling, with or without pain and a rash, may occur at the point where the injection was
given.
A skin rash at the point where the injection was given, or covering a wider area of skin, has sometimes
been seen in situations where the injection has been given repeatedly over a long period of time.
Very rarely, pain underneath and inflammation around the site of injection with accompanying
feverishness has been reported.
